As others have noted, this is an alternate steampunk universe set in the 1910's. A world changed by a single man piercing the veil, and bringing Djinn and magic back into our world. Since that happened about 40 years ago, the djinn have transformed Cairo with their amazing mechanical creations, including robots, flying gliders and trams, and mechanical brains in buildings.
The main character, Fatma, is a respected, if youngest female, investigator in the Ministry of Ministry of Alchemy, Enchantments and Supernatural Entities. She is definitely a maverick, dressing in suits, hats, and carrying a sword cane.
The descriptions of clothing and locations feed the imagination, breathing life into the world and putting it all in your mind's eye. The gradually revealing of the consequences of the mass murder in a secret brotherhood in honor of al-Jahiz, the man who brought back magic to the world, is gripping. The impostor who claims to be al-Jahiz has a dramatic flair that makes everything so much more cinematic. There are more than enough plot twists to keep you guessing until the end, and in the end you are left wanting more of this fantastical world and this amazing investigator.
My one criticism is, of course, Fatma has to save the world.
Again.
What does that leave her for an encore?
All said, the book is a fun romp with descriptions that you can taste and see in your mind's eye. There are multiple strong female characters, which definitely gives the book a distinct flair.
I only give 5 stars to books I think I will read again, and this fits into this category easily due to the cinematic world-building, enchangint character arcs, and gripping adventure.
